Coding system, coding method and coding apparatus

Abstract

A video-coding apparatus acquires apparatus information from a connected external apparatus and automatically registers the external apparatus. Programs may be encoded in a file format appropriate for at least one external apparatus registered for the same program. A coded video file may be generated and stored. When the external apparatus is connected, a previously generated coded video file may be selected for playback by the external apparatus.
